CONVEYER MECHANISM.

SPECIFICATION forming part of Letters Patent No. 678,667, dated July 16, 1901. Application filed January 29, 1901. Serial No. 45,190. No mocleL) To ctZZ whom it may concern:

Be it known that I, SAMUEL MICHAEL JENKS, a citizen of the United States, and a resident of Madison, in the county of Lake and State of South Dakota, have invented a new and Improved Conveyor Mechanism, of which the following is a full, clear, and exact description.

This invention relates to a conveyer mechanism designed especially for handling hay and other material which is carried overhead from point to point-for example, for transferring hay from a wagon to the interior of a barn.

The invention comprises a track and a carrier thereon, the latter having peculiarly-arranged guide-sheaves carrying both parts of a loop in the end of the haul-rope, such parts of the loop running freely over the sheaves and the bight of the loop being engaged with certain novel automatic interlocking slingpulleys, so that when the haul-rope is drawn upon the loop runs over the carrier and serves first to bring the sling-pulleys into interlocked engagement, next to raise the sling-pulleys and the load up into engagement with the carrier, and finally to haul the carrier, slingpulleys, and their load along the track.

This specification is the specific description of one form of the invention, while the claims are definitions of the actual scope thereof.

Reference is to be had to'the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the views.

Figure 1 is an end elevation showing the carrier and the sling-pulleys and indicating the loop in the haul-rope by dotted lines. Fig. 2 is a section on the line 2 2 of Fig. 1. Fig. 3 is a sectional view showing the slingpulley sections locked with each other. Fig. 4 is a sectional view of the same parts, showing them separated. Fig. 5 is a sectional View on the line 5 5 of Fig. 3. Figs. 6 and 7 are respectively end and side elevations, showing-the arrangement of the looped haul- -rope with respect to the carrier and slingpulleys; and Fig. 8 is a view of the haul-rope,

' showing the loop therein.

(1 represents the carrier, and b the track, whereon the carrier runs. The carrier has at each side sheaves a, the axes of which lie in essentially transverse alinement and over which respectively run the two parts of the loop or elongated eye 0, formed in the end of the haul-rope c. The haul-rope is indicated bydotted lines in Figs. 1, 3, and at. The rope is guided to and from the sheaves a by guidesheaves a which are mounted on brackets a projecting from the carrier. Guards a are supported rigidly on the carrier and extend over the sheaves a to hold the haul-rope thereon. The sling-pulleys are arranged in two sections, (designated (Z and e, respectively,) these sections comprising suitable frames or shells, each formed of two cheek or side pieces fastened rigidly together and spaced apart for the reception of certain hereinafter-described mechanism. The section at of the sling-pulleys carries a sheave d, and the section 6 carries a sheave e, which sheaves are similar in construction and are adapted to have the bight of the looped portion 0 of the haul-rope 0 passed around them, as indicated. The sections d and c of the sling-pulleys have downwardly and outwardly disposed extensions d and 6 respectively, which are formed with hooks d and c adapted to engage and hold the bails or other devices which are attached to the load for raising it. Latches d and e are provided for the hooks d and e to hold the bails in engagement with the hooks. The section 6 of the sling is provided with an eye f, adapted to en gage with the carrier at and to be releasably held thereby, owing to the action of certain interior mechanism described and claimed in my copending application for patent on an overhead carrier, patented April 30, 1901, Serial No. 673,270.

Pivotally mounted in the section e are two latches g, which are duplicates in construction and which are carried on a pin g common to each, the latches being held apart by a spacing-sleeve 9 mounted on the pin. The movement of the latches g is limited by the studs g formed on the cheek or side pieces of the frame of the section 6, and each latch g is provided with a toe gtat its lower portion. This toe is arranged to be engaged by a roller 71, carried between the cheek-pieces of the section d, whereby the latches are held in the position shown in Fig. 3, it being obvious from said view that as long as the roller h is engaged with the toes g of the latches pivotal movement of the latches will be impossible. The latches are designed,respectively,to Work with studs t, formed on the cheek-pieces of the section 01 of the sling, the upper extremities of the latches having double beveled portions acting automatically to engage and disengage the studs 1'. The cheek-pieces of the sections of the sling-pulleys are constructed, respectively, with downwardly-disposed eX- tensions d and 6 which carry transverse rollers d and 0,". These rollers are adapted to bear under the rope c and hold the sections of the sling properly engaged with the rope,

and by these means the two sections are held in position properly to engage each other. The framing of the section 6 is cut away to receive the roller h and studs 11 of the section at when the two sections are locked together, as shown in Figs. 1 and 3. This roller h bears on the haul-rope and not only serves to engage the toe g to hold the catch active, but also guides the section din its movement toward the section 6, causing the elements i and g properly to meet each other.

As best shown in Figs. 6,7, and 8, the loop in the haul-rope is formed by doubling the end of the rope back on the standing part and fastening the end thereto by a clamp 0 which may be of any desired form, or, if preferred, the end of the rope may be joined to the standing part by an eye-splice or a rope-bend. The two parts of the loop 0 are passed, respectively, over the sheaves a on the carrier and then downward past the guide sheaves a and around the sheaves d and e of the sections of the sling-pulleys. 'When the haul rope is drawn upon so that the carrier and sling-pulleys are engaged, the parts will assume the position shown in Figs. 6 and 7. When the haul-rope is slacked up and the mechanism of the carrier actuated to release the slingpulleys, (an operation which I do not specifically describe in this application,) the slingpulleys will be free to drop from the carrier, causing the loop 0 of the haul-rope to run over the sheaves a and permitting the sling-pulleysto reach their lower position. The length of the loop on the haul-rope depends upon the vertical distance that it is desired the slingpulleys should travel, to which should be made a slight addition, allowing for the horizontal movement of the sections of the sling-pulleys toward and from each other. In this connection it should be understood that the load is first engaged with the sling-pulleys and lifted up to the carrier, and this therefore necessitates the above-referred-to vertical travel of the sling-pulleys.

Assuming that the loop 0 of the rope c is slack and that the roller h is no longer held firmly engaged with the toes g of the latches g, it will be seen that the sections of the slingpulleys may readily be disconnected from each other. This is shown in Fig. i. The hooks d and e may now be engaged with the sling, which is passed around the load, (supposing the apparatus to be working with hay,) and then when strain is applied. to the loop in the haul-rope the action of theloop will draw the sections of the sling-pulleys together, causing the studsi to ride under the beveled upper ends of the latches g, and further causing the roller h to engage the toes g thus holding the latches in locked position. The upward movement of the sling will now begin and continue until the sling reaches the carrier, whereupon the eye f will be locked with the carrier and the whole mechanism will begin to move along the track. WVhen the sling;pulleys are released from engagement with the carriers, the pulleys may be dropped from the same by slacking up on the haul-rope, and when the tension of the rope is completely relaxed the sections of the slingpulleys may be readily moved apart, so that the hooks d and e may be disengaged from the sling which carries the load. It will be observed that the sections of the sling-pulleys are automatically locked together and unlocked, these operations depending solely upon the pressure of the roller h on the toes g of the latches. Concerning the manner in which the hooks d and e are engaged with the load, it is not necessary for me to explain fully. It is sufficient for me to say that the hooks may be engaged in any desired manner with the load. Generally when handling hay a sling is passed around the body of hay to be lifted, and with this sling the hooks 61 may be connected. The sling is arranged in such a manner that when strain is applied to the sling it is compressed around the load of hay and the sections of the sling-pulleys are permitted to move into locked engagement with each other, as explained above.-

Having thus described my invention, I claim as new and desire to secure by Letters Patent-- 1. In sling-pulleys for conveyer mechanism, the combination of two sections adapted to be engaged with the load, a latch mounted on one section and adapted to engage a part of the other section to hold the two together, and a member carried on the second section and engaging the latch to hold it in locked position.

2. In sling-pulleys for conveyor mechanism, the combination of two sections adapted to have connection with the load, one section being provided with a stud, a latch mounted on the other section and adapted to lock with the stud, and a roller carried by the first-named section and arranged to engage the latch to holdit in locked position and also acting to engage the haul-rope.

3. In sling-pulleys for conveyer mechanism, the combination of two sections provided with means for engaging the load, one section having a stud thereon, a latch pivotally mounted on the other section and provided with a toe, the latch serving to engage the stud, and a member carried by the first section and arranged to engage the toe of the latch to throw the latch into locked position.

4. In sling-pulleys for conveyer mechanism, the combination of two sections each provided with means for engaging the load, one of the sections having a double beveled stud thereon, a latch mounted on the other section and having a double beveled end ar ranged to lock with the stud in the manner specified, and a member carried on the firstnamed section and adapted to engage the latch to throw it into locked position.

5. In sling-pulleys for conveyer mechanism, the combination of two sections adapted to engage the load, locking devices for holding the sections engaged, sheaves mounted on the-sections and serving to carry a rope for supporting the sling-pulleys, and guiderollers carried on the lower parts of the sections and engaging the rope at points between the sheaves to hold the sections in the proper position for engagement and disengagement.

6. A carrier adapted to be used with the sling-pulleys of conveyor mechanism, said carrier having at each side a sheave serving to carry the parts of a looped haul-rope, and said sheaves lying with their axes transverse to the line of movement of the carrier.

7. A carrier for conveyer mechanism, having at each side a sheave serving to carry the parts ofa looped haul-rope, and guide-sheaves respectively arranged adjacent to the firstnamed sheaves and disposed ed gewise thereto.

8. A haul-rope for conveyor mechanism, having its carrier-engagin g end turned back on the standing part and fastened permanently thereto to form a loop or eye, all parts of which move with and as an active part of the haul-rope, for the purpose specified.

9. In a conveyer, the combination of a track, a carrier running thereon, a sling-pulley, and a haul-rope having one end turned back on the standing part and permanently fastened thereto to form a loop moving bodily with the haul-rope as an active part thereof, said loop having its two parts arranged to run on the carrier, and the bight of the loop being engaged with the sling-pulley.

10. In a conveyor, the combination of a track, a carrier running thereon, sling-pul leys, and a haul-rope having one end turned back on the standing part and permanently fastened thereto to form a loop moving bodily with the haul-rope as an active part thereof, the parallel parts of said loop being arranged to run on the carrier and the bight of said loop being engaged with the sling-pulley.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
